i broke my heel a couple years ago & it didn't set properly so i have to wear an insole for support & anything with a heel hurts like mad after a couple of days, so its mostly trainers or docs, but my 3rd pair of docs have just got a hole in them they don't seem to be as waterproof as they were 25 yrs ago either. does any one know of any work ware with flat soles like docs have please
